following BUG() is started when coda is included into kernel. I have not
tried module, but i bet it will couse the same error.
coda_init_inodecache runs kmem_cache_create which couses oups.
Removing following lines from slab.c renders system stable.
But this is not a cure. As i am not using coda it self, i really don't
know if it is running stable.
slab.c snip:
/*
* Always checks flags, a caller might be expecting debug
* support which isn't available.
*/
/*
if (flags & ~CREATE_MASK){
printk("dupa2\n");
_BUG();
BUG();
}
this is in kmem_cache_create fn.

Although I don't run the -bkXX releases, as far as I can see this is not
related to anything in Coda bug, but probably a missing change to slab.c.
A flag was added to the slabcache to identify reclaimable slabs. I can
see how this BUG would get triggered if your kernel was linked with an
old version of slab.o or is missing the SLAB_RECLAIM_ACCOUNT related
changes in slab.c.
Maybe "make clean ; make bzImage modules" will fix it?

I am allways doing that in case of problems. So this is not a case, I
bet this is missing patch for slab.c. Becouse this part i showed (along
with mine two debug lines) does not look to good.
